| Fixed Magnification Lens / Variable Focusing Lens |
|
Applicable to various purposes as inspection instrument, e.g. mounted devices for precision components, substrates, or LCD etc..which helps factory automation or QC standardization.
Variable focusing lenses(conjugate distance changes according to magnification)are available as well. |
| High Resolution Lens |
|
While the objects are in miniaturization, the needs for high-resolution are increasing according to the image processing technology development. We offer custom lens solutions to meet our customer requirements.

| Zoom Lens (Including: Motorized Zoom Lens) |
|
| You can select any magnification arbitrarily without exchanging the lens. Particularly the motorized zoom lens offers high durability and high accuracy in the zooming position, thanks to the biaxial direct acting drive system with the precise ball screw and the stepping motor, which is different from the ordinal cum system. The illumination unit (coaxial/oblique illumination), the drive controller, and the software for variable magnification are to be supplied optionally. |
|
 |
| Telecentric Lens |
|
| Telecentric Optical Systems offer minimal fluctuation in magnification over changes in working distance, which allows for effective and even coaxial illumination. It is very well suited for precise measurement or monitoring and is employed in many of our optical systems.
